DESCRIPTION:The mapping class group of a surface has an incredibly rich no
 rmal subgroup structure. For this reason\, a traditional classification th
 eorem for normal subgroups of mapping class groups\, in the form of a comp
 lete list of isomorphism types\, is almost certainly out of reach. However
 \, we might hope to gain some insight via certain invariants of normal sub
 groups. In this talk\, we will view the automorphism group as an invariant
  of normal subgroups\, and give a survey of known examples providing evide
 nce for a conjectured classification of normal subgroups based on recent j
 oint work with Dan Margalit\, and including constructions due to Dahmani-G
 uirardel-Osin and Clay-Mangahas-Margalit.
